The low temperature magnetic properties in the quasi-one-dimensional system, (EDT-TTF)2AuBr2, were investigated by using 1H-NMR and ESR techniques. (EDT-TTF)2AuBr2 undergoes an SDW transition at 16 K. At 6 K, an anomalous second-peak of 1H-NMR spin-lattice relaxation rate, 1H-T1-1, in the SDW phase has been observed. An additional increase of 1H-NMR absorption line and gradual decrease of spin-spin relaxation rate, 1H-T2-1, were observed below 6 K. The magnetic properties of the SDW phase observed in the present salt are discussed from microscopic points of view.
